Process for the dimerization/oligomerization of mixed butenes over an ion-exchange resin catalyst

Mon, 01 Jun 2015 13:30:59 -0400

Processes for the effective dimerization and oligomerization of a mixed butenes feed using an ion exchange resin based catalyst are provided. The dimerization and oligomerization processes produce highly branched C8 and C8+ olefins (e.g., C12, C16 and C20 olefins) which could be used as superior fuel blending component for higher...



Oligomerisation of olefins for the production of synthetic fuel

Mon, 01 Jun 2015 13:30:59 -0400

A process for producing the fuel composition comprises the oligomerisation of olefins over an oligomerisation catalyst. In addition the invention relates to a process for producing hydrocarbons comprising contacting one or more olefins with an oligomerisation catalyst in a reaction zone under conditions sufficient to cause oligomerisation of olefins, and...



Process for the preparation of an olefin product

Mon, 01 Jun 2015 13:30:59 -0400

A process for the preparation of an olefin product, which process comprises the steps of: a) converting an oxygenate feedstock in an oxygenate-to-olefins conversion system, comprising a reaction zone in which an oxygenate feedstock is contacted with an oxygenate conversion catalyst under oxygenate conversion conditions, to obtain a conversion effluent...



Increased conversion of recycled oxygenates in mto

Mon, 01 Jun 2015 13:30:59 -0400

A process is presented for increasing the conversion efficiency of oxygenates to olefins. The conversion of oxygenates recycles unconverted oxygenates and oxygenate by-products to a second reactor unit. The present of oxygenate by-products decreases the efficiency of the methanol to olefins reaction, and passing recycled oxygenates to a second reactor...

Mon, 01 Jun 2015 13:30:59 -0400

A process is presented for the separation of iso-olefins from a hydrocarbon mixture comprising paraffins and olefins. The process includes an adsorption separation system, wherein the adsorbent is selected according to the properties of the material that is desired to be adsorbed. The process also includes a selection of a...



Unsupported metal substituted heteropolyacid catalysts for dimerization and/or oligomerization of olefins

Mon, 01 Jun 2015 13:30:59 -0400

The present invention relates to unsupported metal (e.g., cesium) substituted heteropolyacid catalyst compositions useful for the production of butene dimers and/or oligomers from a mixed butenes feed, in which, under mild conditions, all isomers of mixed butenes produce highly branched C8 and C8+ olefins, useful as octane enhancers....
